I really like this idea from Cal Newport that social media is ultra-processed content, analogous to ultra-processed food:

the users of social media platforms simulate something like the food scientist’s ability to break down corn and reconstitute it into hyper-palatable edible food-like substances

Mike Masnick argues that social media can’t be inherently harmful, saying, “The complaints here are with speech.” but while Doritos & Pepsi are (technically) food, that doesn’t mean they’re good for you
